I picked up some 7mm 168gr SAAMi hydrids, after the initial testing I was in short tickled, 2nd outing trying different primers one primer stood out so well my grouping mirrored my notes from the shooting bench! I.e. called one 1/2" left and 1/4" low, another good center bull, another 1/2" left, another 1/4" low ect. That's just what measured on my 200yrd target. These things shoot waaaay better than I do!
